项目摘要

The demand for efficient and accurate machine tools and machining technology is rapidly increasing in recent years. The intensive manufacturing technology capable of the whole machining at one setup allows machine tools to realize the efficient and accurate machining. The study proposes a new machining method of combining sophisticated. 5-axis control machining with 6-axis control, one using non-rotational cutting tools. However, the cutting speed of 6-axis control machining is low, which causes the deterioration of machined surface quality. Thus, the ultrasonic vibrational cutting was employed to solve the problem. The study is summarized as follows :1. The-main processor to generate cutter path (CL) data for 6-axis control machining, based on workpiece shapes defined by 3D-CAD system, was developed, especially for character line machining and asymmetric grooving, taking account of collision avoidance between tool and workpiece.2. Cutting experiments by use of a vibration tool were carried out on a 6-axis control machining center with NC data converted from CL data by use of our own post processor. As a result, the workpiece with fine surface quality can be obtained.3. A part of the integrated multi-axis control CAM system was achieved to perform the efficient machining ,by unifying the effective 5-axis control CAM system and the 6-axis control one developed in the study.

近年来，对高效和精确的机床和加工技术的需求迅速增加。一次装夹完成全部加工的集约化制造技术使机床能够实现高效、精确的加工。研究提出了一种新的加工方法，结合复杂的。5-轴控制加工与6轴控制，一个使用非旋转刀具。但6轴控制加工的切削速度较低，导致加工表面质量恶化。为此，采用超声振动切削的方法来解决这一问题.主要研究内容如下：1.基于三维CAD系统定义的工件形状，开发了六轴数控加工刀位数据生成主处理器，特别是针对特征线加工和非对称切槽加工，考虑了刀具与工件之间的碰撞避免.在六轴数控加工中心上进行了振动刀具切削实验，并利用我们自己的后置处理器将CL数据转换为NC数据。从而获得表面质量优良的工件.将本研究开发的有效的五轴控制CAM系统与六轴控制CAM系统相结合，实现了多轴控制CAM系统的一部分，实现了高效加工。
